IMPROVEMENT. IN.MAQH INER Y IOR PRiN'I-ING-OIL-OLOTH, 8:9.

The Schedule yoferrcdto in thus Letters Patent and milling :Plrl: 9| 1im To all whom it may concern.-

Be it known that I, inthe county of Essex and State of New Jersey, haveinvented a new and improved'lress for Printing Oil- Glot-hs,Table-Clothes, &c.; and I do hereby declare that the thllowing is afull, clear, and exact descripjionthereof, which will enable othersskilled in the art to make and use the samc,.refercnce being bad to 7the accompanying drawing forming part of this specification. a 1 g Myinvention relates to a-printing apparatus for oil-cloths and-otherfabrics, and consists in certain improvements, which will first hedescribed in connecfiOILWith all that is necessary to a fullunderstanding thereof, and then clearly specified in the claim.

In, the accompanying drawing- Figure 1 representsa side elevation of myimproved oil-clo'th-printing machine. 7

Figure 2 is a vertical longitudinal section of the same. r I

Figure 3 is-alplan or top view of the same.

Figure 4 is adetail vertical transverse section of one of the coloringdevices.

Figure 5 is a detail side view of asectional printing-cylinder. v

Figure 6 isan endview of the same.

Figure 7 is a detail longitudinal section of the clamp for holding thefabric.

Similar letters of reference indicate corresponding parts.

v A, in the drawing, represents themain supporting bed or floor of myniacliine.- Upon it are supported the three main divisions of themachine. These-db visions are-first, the coloring; second, the printing;and third, the cloth-holding machine. Only the printing division issecured upon a stationary frame, B. The other divisions are upon slidingframes 0 and D respectively.

In the'fixed frame B are hung three (more or less) horizontal axles E EE, all vertically above each other.

Upon each axle E is fitted a printing-cylinder, F. When a cylinder, F,has the full length of the axle between the upright bars of the frame B,it is intended to printthe full width of the fabric.

The cylinders may, however, as in fig. 5, be made in shorter pieces, toprint but one-half or one-third of the width where the design isrepeated in a horizontal direction. Insthis latter case a shortcylinder, F, is fitted upon an axle, E, andislocke'd to either end, orto the middle of the same,.by means of aspringcatch, a, which is securedto one end of the cylinder,

as shownin fig.'-6.

The axle E. is provided with a feather, b, to prevent the cylinder fromturninglcosely on it. This Josnrn KRAFT, of h icwark,

feather" has notches to receive the spring catch, as indicated in fig.5.

' The pinsc c,"w-liicl'r imprintt-he required design upon the fabric,are set upon the faces of the printingcylinders F or On the cylinder F,which extends throughout the entire width of the frame, these pics sweetso as to produce but one half the design for each color, as the reverseof it can be printed by the same pins, by. reversing the position of thefabric.

The fabric to be printed is held on a -frame,G, which is, by a pin, H,pivoted to the sliding frame 1). Fonr.(more or less) horizontal rollers,d d, are hung in-the frame G, and-over them the fabric I is drawn insuch manner that it is properly stretched in a straight line, directlyinfrOnt-ot' the priuting-cylin-- 'ders.

' lt'is veryimportantthat'the cylinders F should be so set that theirrespective designs-arc applied to the fabric in the desired succession.Forthis purpose I apply to the end of each axle E a worm-wheel, e,firmly keyed to the axle. I

This worm-wheel gearsinto a worm, j, which is atfixed'to a wheel, 'g,hung loose, upon the axle. The wheels 9g of the several'a xles areconnected with each otherby meaus'of a connecting-rod, h, which isattached to crank-pins, t i, that project from'said wheels, as shown.The cylinders will thus all revolve simultaneously.

"In order to set the printing position of each cylinder with referenceto that of all others, it will only be 'necessary to turn the worm f ofsuch cylinder, and to thereby turn the axle -E within. the wheel g,without disturbing-the latter,-

1 When the fabric hashccn printed with one-half design, theframe GiS-turned on the pin H to reverse the position of the fabric. The motion ofthe fabric is, atthe"'same time, also reversed, and thereby the half ofthe design is produced.

Motion -is imparted 'to one of the rollers, 11, by means of'agear-wheehj, on the frame -B, the said gear-wheel meshing into=asimilar ,wheel, K, that is on the end of the rdller cl. 'On the oppositeend of another roller, 11, is} mounted another toothed wheel, z,-which,when the frame G is reversed, is brought into contact with the wheelj,to provide for the further but reversed motion of the fabric.

The fabricto be;printed is, from below, brought to the frame G,'andsecured to pointed pins m m that project from a bar, n,.the said barbeing secured to a belt,' o, which passes around the roller 02. Thefabric. is then laid around the said belt 0, and is then secured to atoothed roller, J, which is hung in the frame G as shown. By turningthe'said roller J the fabric will be'stretched, and can then be clamped,with its other end, to the belt 0', by a toothed hinged clamp, L. It isthen cut off orscparated from the roller J, and in position. forprinting. A pair], 1), meshing into a ratchet-wheel, 'r, on one of therollers (1,, prevents the fabric from getting loose from the pinsm-{WllllG it is being stretched by the roller J.

Some or all of the rollers cl are hung in slots and adjustable therein,to keep the belt 0 properly stretched.

The frame 1) is, with all 'of its appendages, made to slide on the bedA, and is, by a rack, 8, United with a worm, M, by means of which'it canbe carried away from the printing apparatus, as in fig. 2, to allow thesame to'be reached.

The coloring part of the machine is all arranged in the sliding frame 0,which is, bya rack, t, and toothed wheel, N, made adjustable toward oraway from the printing frame; also, for the purpose of allowing accessto all the parts.

The-coloring apparatus for each printing-roller consists of an endlessapron, O, hung upon two rollers, P and It, of whichthe lower one, P,turns in a reservoir or'yat, S, that contains the color. Each reservoiris made to slide into its place by being suspended from rails, 21 a,that are formed on the frame 0. By

means of screws, '0 c, which are arranged in cars at the ends of eachreservoir, the position of each reservoir can be adjusted to be more orless oblique. Thus, if the apron should happen to be slightly thicker onone side than atthe other, so that it might tend to run off the rollers,it will be necessary to shift the lower roller with the reservoir, forcounteracting this effect. v

A sliding scraper, T, is arranged on each apron O, for the purpose ofscraping the superfluous color from the same. It can be adjusted forgreater or lesser pressure by means of screws or, and is drawn againstthe apron by springs x.

The upper rollers R are at their ends provided with toothed wheels, 3,which mesh into the wheels g on the corresponding axles E,'as shown infig. 1.

Each roller R is hung in slides, 11 y, that are fitted into the frame 0,as indicated in fig. 4.

Having thus described my invention- I claim as new and desire to secureby Letters Patent sectional printing-rollers I F, which hare spring'{catches a, as set forth.
